Leaving The Ranger Community....Whoa Is Me....Whoa Is Me.....

[ctechbob]

Towing travel trailers around these days is the great MPG equalizer. Especially when it comes to comparing turbo to turbo and NA to NA motors the results are always close to the same within a margin of error. Especially with GDI and 8/9/10 speed transmissions, there's just not a lot of variation.

10MPG with no wind, and if you really want to feel your wallet squeal, tow a travel trailer across the upper midwest heading in to a 20-30 mph headwind and get back with me.

I dipped into the 5's, even slowing way down, it was brutal.

Ohh yea, @Grumpaw, dunno if you did it with the Ranger, mine hardly ever shifted into 9 or 10 anyways so I rarely bothered, but the 3.5 has plenty of grunt to run in 10th, but you'll pick up about 1-2mpg running in 8th instead. Only downside (if you can call it that) was my oil temp picked up about 5 degrees. Trans didn't seem to care, it was about the same either way.

Whoa - used as a command to a horse to make it stop or slow down, or to urge a person to stop or wait.

Woe - great sorrow or distress (often used hyperbolically)

Just saying ...

I'm glad that we have an entomologist on the Forum to find the bugs in the posts.

I wonder what the exhaust temp is at the turbo under load. My Cummins ISX 15 would hit 1060ºF under sustained heavy load, but that was at 28-30psi boost.

It gets hot!

I never got around to measuring the temps on turbos installed on Miatas, but the oil would quickly coke up the oil input and return lines if you didn't cool them sufficiently. We used both coolant and oil to keep temps under control. We had to be very careful with input lines. The heat would bake even the best quality hoses over time. We moved to metal lines before it was over. And we were only running 10-12 PSI. I heard/read that Rangers run into the low 20PSI range.

We even had to install a heat shield to keep the paint on the hood from baking/discoloring!

Dunno, it has been a busy summer and I haven't had time to explore what all information is available from the truck. Just guessing by the gauge on the dash though, running in 10th on flat level ground at 70 I'd estimate it is running about 8 psi, in 8th it is at least half that, so I would imagine temps are well under control either way. Max on the engine is something like 20 and you're never ever there for long. Even towing if you floor it you're doing highway speeds in no time so sitting there at max boost just never happens for very long.
